CONVEYER.

SPECIFICATION forming part 0f Letters Patent No. 275,758, dated April 10, 1883.

Application filed March 12, 1883. (No model.) i

To all whom it may concern Be it known that I, WILLIAM H. FELT- HOUSEN, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented new and useful Improvements in (lonveyers, of which the following is a specification.

In the Letters Patent granted to me on the 3d day of October, 1882, No. 265,491, I provide a machine for cleaning and grading peas in which lthe peas are elevated to a cleaningscreen, and then delivered to the upper one of a series of perforated. grading-cylinders. rlhe elevator disclosed in my patent alluded to has not proven generally satisfactory in operation 5 and it is the object of my present invention to avoid the existing objection and provide novel and efcient means for conveying the peas to the pea-cleaning screen in the patent mentioned without danger of rupturing or breaking the delicate structure of young and fresh peas. This I accomplish by means of a spirally-hanged conveyer-shat't located within a closed cylinder having at one end a hopper and a throat leading from the hopper tothe interior of the cylinder, such throat being composed of walls which are arranged diagonally to the axis ofthe cylinder in such manner that the peas can pass between the curved spaces formed by the spiral flange without danger ot' the outer edges of the flange shearing the peas in halves or otherwise cutting them between such edges and the lower edge of the wall of the hopper-throat, which extends in the direction the peas are to be moved.

Theinvention embraces other features, which will be fully hereinafter described and claimed, and illustrated in the accompanying drawings, in which- Figure l represents a plan view of a conveyer constructed in accordance with my'invention, the hopper itself being omitted; Fig. 2, a longitudinal vertical sectional view on the linezow of Fig. l, the hopper being in position; Fig. 3, detached views of the parts.

The cylinder is composed ot' two or more longitudinal semicircular sections, No. 1,each provided at its edge with laterally-projecting perforated ears'2, through which pass pins or bolts 3 for joining the sections together. The longitudinal conveyer-shaft el is constructed 'with a continuous spiral flange, 5, rectilincar in cross-section, and such llange rests directly upon the lower portion or section of the cylinder, whereby no intermediate supporting-bearings for the shaft itself are rl quired along the length of the cylinder, which is important, in that by this means a continuous unobstructed channel is provided throughout the length of the cylinder, which avoids bringing the peas in contact with any fixture in the cylinder that would break or rupture them. One end of the conveyer-shaf't is formed or otherwise constructed with a circular imperforate disk or wheel, 6, which not only serves to close the end of the cylinder, but also provides means for revolving the conveyer-shaft, which may be done bya hand-crank, 7, or through the medium of gearing. The upper portion or section of the cylinder is constructed with a rectilinear opening arranged diagonally with reference to the axis of the same, and from they obliquely, as the conveyer moving the peas forward would be only liable to shear them in halves by catching them between the outeredge of theconveycr-ila-ngeandtheloweredge of the hopper-throat. This is avoided by locating the advance wall obliquely, as this construction causes the lower edge of such advance wall to extend in the direction in which the peas are moved, and hence if the peas fall between the flange and advance Wall they will be caused to gently and smoothly glide along the lower edge of said wall and fall downward into the lower portion or section of' the cylinder, and by the spiral flange be conveyed to the other end of the cylinder and discharged upon the pea-cleanin g screen hereinbefore alluded to.

The hopper 11 is of any suitable construction, and is attached to the upper edges of the walls composing the hopperthroat. As here shown, the cylinder-sections are ot' cast metal,

IOO

the upper section being formed integral with the walls composing the hopper-throat; but while such is e desirable construction, I do not wish to be understood as confining my invention thereto.

By the construction of conveyer herein set forth l provide simple, eticient, and reliable means for uniformly lifting the peas and uniformly discharging them upon the cleaningscreen, it being understood that the conveyershaftis rotated at slow speed to avoid too tically closed along its length, of a spirallyflanged shaft having at one end au attached disk or Wheel for closing one end ofthe cylinder, and a hopper and hopper-throat communicating with the cylinder adjacent to the disk or wheel on the conveyor-shaft, substantially as described.

3. The combination, with the cylinder composed of two longitudinal sections detachably connected, and the upper section constructed with a hopper-throatway the advance wall of which is located obliqucly to the axis of the cylinder, ot' a spirally-tla-nged conveyer-shaft the planes of which are in contact with the in terior surfaces ot' the cylinder to support the shaft Without intermediate supporting-bear ings thereof', substantiallyr as described.

l'n testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

WM. H. FELTHOUSEN.
